Answer 1

关闭 synaptic 包管理器，“sudo apt install”命令将自动继续。

您不能同时打开两个与 APT 包管理系统配合使用的不同应用程序。

是的，我经常看到和你一样的消息;)

Answer 2

您可以使用进程 ID 强制关闭进程。

如果你的终端显示，

Waiting for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 43843 (synaptic)

那么，您的情况下的进程 ID 是43843。

要终止该进程，请使用此命令，

sudo kill 43843
